FOLDING BOX.

SPECIFICATION forming part of Letters Pa nt N0. 770,915, dated September 27, 1904. Application filed November 6, 1903. Serial No. 180,186. (No model.)

To all whom, zit may concern.-

Be it known that I, GEORGE MAUNsELL- SMYTH, a subject of the King of Great Britain, residing at 15 Hope Park, Bromley, county of Kent, England, have invented a new and useful Improvement in Folding Boxes, of which the following is a specification.

The improvements relate to that kind of paper boxes, and it may be to their covers,which are formed of flat material having certain scored or creased lines and cuts enabling them to be shipped and stored in their fiat condition and when needed for use readily set up into box or box and cover form without the use of extraneous fasteners.

In the drawings, Figure 1 illustrates the box proper in its flat condition with the needed scored or creased lines and cuts. Fig. 2 is a perspective view of the box partially set up for use, and Fig. 3 is a sectional view.

The corrugated paper employed is preferably that known in the market as cellular board that is to say, wherein the corrugated sheet is interposed between two fiat sheets and the three united to form a single sheet. Other suitable paper or material may of course be used.

The box is formed of a flat rectangular sheet A, provided with the four parallel creased or scored lines 1 2, the lines 1 beingin duplicate to facilitate the inward folding of the outer strips 6. These lines form a bottom 5 and duplex side strips 6 7 on each side of the bottom. The ends are formed by additional strips B, united to the bottom portion by wire staples 10, cement, or other binding material. These ends B are each provided with a creased or scored line 11 and with side scored lines 12, the latter forming the side or corner flaps 14. That portion 16 of the end strips united to the bottom lays on the upper surface, so that the edges of its ends 31 (owing to the elasticity of the material,which tends to curve upwardly, see Fig. 3,) form looks or abutments for holding the box sides in place when the box is set up for use.

In setting the box up for use the two ends B are bent upward on the creased lines 11 at right angles to the bottom 5 and portion 16, and the end flaps 14 are turned inwardly at right angles to said ends. The duplex side pieces are then turned upwardly on the creased lines 2 against the end flaps, and the outermost strips 6 are then turned inwardly and downwardly to lie parallel with the strips 7, so that the end flaps 14 areconfined between the two strips 6 and 7. The lower edges of the strips 6 are then forced past the edges 31 of the portion 16 of the end strips, which yield sufficiently for the purpose and then spring back in place to form abutments, holding the side strips 6 firmly in place, as indicated in the partial section, Fig. 3. The flaps 14L are sufficiently long to prevent their being accidentally pulled out from between the side strips.-

Having thus described my invention, I claim- 1. A box formed of a blank comprising a bottom and duplex sides, and ends having corner-flaps held between the folds of said sides, and having integral cross-strips lying upon the upper surface of the said bottom and connected with the bottoms of said ends with their ends abutting the inner folds of the duplex sides and forming abutments for holding the said sides and ends in place.

2. A box formed of a blank comprising a bottom and duplex sides, ends having cornerflaps held between the folds of the duplex sides and having integral cross-strips held between the inner folds of said duplex sides said cross-strips being connected with the bottoms of the ends and holding the sides and ends together.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE MAUNSELL-SMYTH.
